(a) Experimental data of ΔC = C(0T) − C(2T) vs T, plotted with the fits by different gap functions. In the p-wave fitting, we assume the gap function to be Δ = Δ0 cosϕ. Inset shows the expanded view of the fits at low temperatures. Clearly, s-wave model fits the experimental data better. The ΔC/γ n T c is 1.22, very close to the weak coupling BCS value of 1.43. (b) ΔC/T vs T. The solid and dashed lines are fits to the s-wave and d-wave models for \(T < \frac{1}{3}{T}_{c}\), respectively.
